RUDOLF KRAUS, OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF TO CHARLES KRAUS, OF NEW YORK, N. Y.

MACHINE FOR FORMING PLASTIC PATTERNS ON WALL-PAPER.

SPECIFICATION forming part of Letters Patent No. 697,498, dated April 15, 1902. Application filed February 6, 1902 Serial No. 92,790. (No model.)

T0 at whom, it may concern:

Be it known that I, RUDoLE KRAUS, a citizen of the United States, and a resident of New York city, borough of Queens, county of Queens, and State of New York, have invented certain new anduseful Improvements in Machines for Forming Plastic Patterns on Wall-Paper, of which the following is a specification.

This invention relates to a machine for providing wall-paper with patterns in relief, such patterns being composed of a plastic mass which is molded and secured to the paper by By my machine the manufacture of this durable class of Wall-paper is facilitated, so that unskilled labor may be employed, and the output is increased.

In the accompanyingdrawings, Figure l is a front elevation of my improved machine; Fig. 2, a side elevation; Fig. 3, a section of part of the machine on line 3 3, Fig. 2; Fig.

4, a vertical longitudinal section of the moldbox and plunger; Fig. 5, a detail side View of the lever h; Fig. 6, a section on line 6 6, Fig. 5, partly in plan; Fig. 7, a side elevation of the mold-box; Fig. 8, a plan of the same with the cutter removed; Fig. 9, a plan of the paper-clamp; Fig. 10, a detail plan of lever 0; Fig. 11, a face view of the wall-paper ornamented by the machine; and Fig. 12, a section on line 12 12, Fig. 11.

The letter a represents the frame of the machine, that supports the work-table a. Over this table is fed by'hand or otherwise from delivery-reel b the wall-paper A, to which the relief-patterns are to be applied. This paper is adapted to be held firmly upon the table by a frame or clamp c, Fig. 9, which is hinged to the table at c and is held down by a springfinger c To the clamp c is pivoted, by means of lugs d 0 a mold-box cl, the base 01 of which is removably secured by screws d and constitutes a pattern plate or die. This plate is perforated to form any pattern desired, the edges of the perforations being beveled to prevent binding. A pin (1 on each side of mold-box d is adapted to engage a projection or hook c on frame 0, so that the mold-box will take the frame along after having been partly raised.

Within the mold-box d is free to reciprocate a plunger 6, having, preferably, a corrugated lower surface and adapted to engage stops or pins d projecting inwardly at the top of the mold-box. The plunger (2 is reciprocated from the power-pulleyf in the following manner: The pulleyfis coupled to a shaft f by a clutch f that opens automatically at each complete rotation of shaft f, so that the machine is arrested. The clutchf is adapted to be closed by a hand-leverf Upon the shaft f is mounted a cam g, the groove 9 of wh ich is engaged by'a pin 72. on one end of a two-arm lever h, turning on fulcrum b of frame a. The other end of lever h is provided with a tubular socket h in which is free to turn the pin 1) of a forked bearing 1', which is held against withdrawal by a set-screw h and groove 1?. In the bearing vi is hung, by means of trunnionsj', a tubular sleeve j, through which passes loosely a bolt 70, having a threaded lower end. This end engages a threaded sleeve Z, which is connected by a universal joint Z Z to a'lug e of plunger 6. In order to set the plunger so that it always bears upon the surface of the constantly-changing quantity of plastic material in the mold-box, the bolt 70 may be rotated by hand-lever is so as to be screwed into or out of the sleeve Z. Between the hand-lever 7c and the sleeve j is interposed a spring k which permits the plunger to yield under excessive pressure. in conjunction with the sleeve j, constitutes a universal joint between the lever h and the bolt 76. The groove 9 of cam g is so shaped that at each downstroke the plunger is caused to tamp the plastic mass successively for a number of times, this tamping action being effected by the outwardly-projecting camgroove sections 9 In this way the plastic mass is pressed forcibly through the patternplate (1 and against the paper A.

It will be seen that the bearing 2',

In order to separate the molded portion of n. The plate m is provided with a pin m lhat is engaged by the forked end of a lever 0, fulcrumed at 0 to frame a. The lever 0 receives reciprocating movement from shaft 5 f by bevel-gearf and shaft 1), upon which is mounted cam q. This cam is engaged by a pin 0 of lever 0, so that at each rotation of the cam an intermittent stroke of the knife is edected.

The operation is as follows: A length of paper is unrolled from reel b and placed upon table a. The leverf is manipulated to close clutch f and rotate cam g by shaft f. The cam will cause the plunger 6 to descend so as to release screws d and permit mold-box d,

as well as clamp c, to descend by gravity, assisted by spring-finger 0 Thus the paper will be securely clamped to table a beneath the pattern-plate 01 The knife m is with- .20 drawn by cam q and lever 0, and the plastic mass is tamped by the further descent of the plunger, caused by the projecting cam-groove sections g. In this way the mass is pressed forcibly through the pattern-plate and into contact with the paper A. The knife is advanced to separate the molded pattern from the main bulk of the plastic mass and to then form a false bottom within the box above the pattern-plate. The plunger 6 is raised to tilt box 1 upon its hinge by engaging stops (1 and to thus raise the pattern-plate off the paper. During this upward movement the pin m becomes disengaged from lever 0, so as to disconnect the knife from its operating mechanism. When the box d has swung up to such an extent that the pins (1 engage the hooks 0 the clamp 0 will also be raised upon its pivots a, so as to liberate the paper. When the mold and clamp are completely opened, the clutchf is automatically opened to arrest the machine. The finished section of paper A, provided with the molded ornamentations A, is now fed to the left for the length of one pattern, and the operation is repeated. If 5 desired, the paper may be covered in part by an adhesive before being fed underneath the mold-box. The finished paper is dried upon racks in the usual manner and is ready for the market.

WVhat I claim is 1. In a machine for forming plastic patterns on wall-paper, the combination of a mold-box with a pattern-plate, a plunger, and means for raising the pattern-plate, substantially as specified.

2. In a machine for forming plastic patterns on wall-paper, the combination of a mold-box with a pattern-plate, a plunger, and means for raising the mold-box and pattern-plate, substantially as specified.
